clockworkmod recovery

I have a Sprint Zio on 2.2 froyo I am rooted and installed ROM Manager and went to install clockworkmod recovery and got to the screen where you choose your phone model and I saw that the zio is not supported is there something else I can do to backup my ROM?

Update: I played around and found Super Manager and Deleted ROM Manager and I can use this fully to backup everything with su perms works great still looking for custom boots and/or custom zio roms.

Update: Super manager failed but I managed to copy my system.img and recovery.img and shared it with devs over at XDA hopefully Kouch will get us Clockworkmod up soon and source code is also coming very soon getting close to cracking this phone open!
